Therefore, to solve the problems caused from the prior arts is an important issue to the skilled persons in the art.

SUMMARY OF THE INVENTION

One aspect of the present invention is to provide a device with a button restriction element to restrict the motion of the second fixing element and decrease an oblique situation of the button.

According to one embodiment of the present invention, the device comprises a device substance, a button and a circuit board. The device substance has a button opening, and the button comprises a button substance, a first fixing element, a second fixing element, and a driving element. The button substance locates in the button opening and bulges out from the surface of the device substance, the surface has a first side and a second side. The first fixing element fixes on the first side of the button substance and wedges with the device substance. The second fixing element fixes on the second side of the button substance. The driving element locates on the button substance. For example, the circuit board locates within the device substance and has a driving point, which is located correspondingly to the driving element. One aspect of the present invention is that a button restriction element fixes on the device substance in order to restrict the motion of the second fixing element.

When users press the button substance, the button restriction element restricts the motion of the second fixing element to make the driving element drive the driving point of the circuit board. The driven driving point will lead the circuit board to act functions.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Nowadays popular devices as cellular phone, camera, remote controller, and media player generally have at least a button to provide setting functions, but the buttons are easily stuck as always. The present invention provides an advance structure to solve the problem, and thereinafter the detailed description of the present invention is as below.

Referring to FIG. 2 a, which illustrates a schematic view of a device with a button restriction element of one embodiment of the present invention. The device includes a device substance 200, a button 210 and a circuit board 220.

The device substance 200 has a button opening, and the button 210 includes a button substance 211, a first fixing element 212, a second fixing element 213, and a driving element 214. Wherein, the button substance 211, the first fixing element 212, the second fixing element 213 are an integrated as a whole member. The button substance 211 locates in the button opening and bulges out from the surface of the device substance 200, the surface has a first side and a second side. The first fixing element 212 fixes on the first side of the button substance 211 and wedges with the device substance 200. The second fixing element 213 fixes on the second side of the button substance 211. The second fixing element 213 is a cantilever beam and doesn't wedge with the device substance 200. The driving element 214 can locate on the button substance 211 near the first side of the button substance 211. The button restriction element 230 fixes in the device substance 200 to restrict the motion of the second fixing element 213. One embodiment of the present invention, the circuit board 220 locates within the device substance 200 and has a driving point 221, which is located correspondingly to the driving element 214. One embodiment of the present invention, wherein the driving element 214 is a cylinder element, and can be made of rubber material or metal material. One aspect of the present invention is that a button restriction element 230, for example, fixes on the device substance 200 in order to restrict the motion of the second fixing element 213.

Referring to FIG. 2 a, which illustrates an action view of a device with a button restriction element in one embodiment of the present invention. When the button substance 211 is pressed, the button restriction element 230 restricts the motion of the second fixing element 213 to make the driving element 214 drive the driving point 221 of the circuit board 220. The driven driving point 221 will lead the circuit board 220 to act functions.

The button restriction element 230 restricts the motion of the second fixing element 213. As a result, the second fixing element 213 has a support to decrease an oblique situation of the button and avoid the button getting stuck and the driving point 221 being damaged. Only the press action is acted correspondingly, the driving element then contacts the driving point correctly.
